Which one of the following is not an acceptor impurity?
Correct answer: B. Indium
- A. Gallium
- B. Indium
- C. Boron
- D. Arsenic
Explanation
Indium is not an acceptor impurity.Among the options listed, gallium, boron, and arsenic are examples of impurities that act as acceptors when doped into semiconductor materials. They create "holes" in the crystal lattice and contribute to the positive charge carriers within the material.However, indium is a donor impurity, not an acceptor. It introduces additional electrons into the crystal lattice, leading to an excess of negative charge carriers in the semiconductor material.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
